Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a portable photo inkjet printer. Background Technology

[0002] Currently, the portable photo printer market offers products using various methods, including instant photo printing, dye-sublimation, and ZINK paper. These methods share common drawbacks: high printing costs, generally lower print quality (except for dye-sublimation), and a tendency for photos to fade.

[0003] The primary method for photo printing is still inkjet printing. Inkjet printers contain a sophisticated printhead with numerous tiny nozzles. Upon receiving a print command, the printer controls the nozzles to eject ink as extremely small droplets onto the corresponding areas of the paper, based on the image or text information. Through the combination and precise arrangement of different colored ink droplets, a complete image or text is ultimately formed.

[0004] However, inkjet printers are not easy to make small and portable, so a brand new photo printer needs to be developed to fill the gap in the portable photo printing industry and realize instant photo printing. Summary of the Invention

[0005] The purpose of this invention is to provide a portable photo inkjet printer, which aims to solve the problem that existing inkjet printers are not easy to make small and portable, thus reducing the portability of inkjet printing.

[0006] To achieve the above objectives, this utility model provides a portable photo inkjet printer, comprising a middle shell, a paper position sensor, a scraper blade, a motherboard, a rear cover, a battery, a front cover, and a bottom shell assembly.

The flexible plate 114 is mounted on the column of the carriage bracket 110 via an interference fit. The ink cartridge 112 is mounted on the carriage bracket 110 via a hook. The torsion spring 111 on the frame 110 is fixed to the carriage bracket 110, thereby making it easy to disassemble and install the ink cartridge 112 and reliably connect it to the main board 104; the first reduction gear 115 is mounted on the second pin 130, and the small gear of the first reduction gear 115 meshes with the gear on the carriage bracket 110; the second reduction gear 116 is mounted on the third pin 131, and the small gear of the second reduction gear 116 meshes with the large gear of the first reduction gear 115; the first motor 117 is mounted on the sheet metal bracket 109 and meshes with the second reduction gear 116.With this design, the ink cartridge 112 can rotate within a 180° range, achieving fan-shaped printing. The advantages of fan-shaped printing are that rotation is simpler than translation, accuracy is easier to achieve, and the ink scraping and sealing are located on both sides of the middle shell 101, resulting in a smaller overall printer size. The width required for a translational design is reduced by 20%, thus increasing the portability of the portable photo printer by using fan-shaped printing.

[0029] Secondly, the mounting bracket 119 is fixedly connected to the sheet metal bracket 109 and located on one side of the sheet metal bracket 109; the paper feed roller 118 is disposed on the mounting bracket and located on one side of the mounting bracket 119; the drive shaft 120 is connected to the mounting bracket 119 and located on one side of the mounting bracket 119; the transition gear 121 is disposed on the sheet metal bracket 109 and meshes with the drive shaft 120, and is located on the side of the sheet metal bracket 109 near the drive shaft 120; the third reduction gear 122 is disposed on the sheet metal bracket 109 and meshes with the transition gear 121, and is located on the side of the sheet metal bracket 109 near the transition gear 121; the fourth reduction gear 123 is disposed on the sheet metal bracket 109 and meshes with the third reduction gear 122, and is located on the side of the sheet metal bracket 109 near the third reduction gear 121. The second motor 124 is mounted on the sheet metal bracket 109 and meshes with the fourth reduction gear 123, and is located on the side of the sheet metal bracket 109 close to the fourth reduction gear 123. The paper feed roller 118 is mounted on the mounting bracket 119, which is mounted on the sheet metal bracket 109 and connected to the rear power mechanism via the transmission shaft 120. The transition gear 121 is mounted on the fourth pin 132 and meshes with the gear of the transmission shaft 120. The third reduction gear 122 is mounted on the fifth pin 133, and its pinion meshes with the transition gear 121. The fourth reduction gear is mounted on the sixth pin 134, and its pinion meshes with the large gear of the third reduction gear 122. The second motor 124 is mounted on the sheet metal bracket 109, and its gear meshes with the fourth reduction gear 123. The bottom shell 125 is connected to the middle shell 101 and is located on one side of the middle shell 101; the compression spring 126 is disposed on the bottom shell 125 and is located on one side of the bottom shell 125; the pressure plate 127 is disposed on the compression spring 126 and is located on one side of the compression spring 126. The pressure plate 127 can push the photo paper onto the paper feed roller 118. Driven by the second motor 124, the photo paper on the topmost paper feed roller 118 begins to enter the printing channel. After the paper position sensor 102 detects it, the print head begins to print. Before printing is completed, the ink cartridge 112 flashes ink and scrapes off the ink left on the print head by the ink scraper 103. After printing is completed, it returns to the far right, the front cover 107 is removed, and the ink cartridge 112 is replaced; the bottom shell 125 is pushed open, and the photo paper is placed in.

[0030] Meanwhile, the fan-shaped window 128 is located on one side of the sheet metal bracket 109, and the fan-shaped window 128 is opened on the sheet metal bracket 109, so that the inkjet head on the ink cartridge 112 can spray ink onto the photo paper.

[0031] Finally, the sealing bracket 108 is disposed on the middle shell 101 and located on one side of the middle shell 101. The sealing bracket 108 consists of a sealing gasket, a bracket and a tension spring, and is installed on the right side of the middle shell 101. The sealing bracket 108 indicates that the whole machine has a sealing function, which is a conventional design in the field and will not be described in detail here.

[0032] When using a portable photo inkjet printer according to this embodiment, a first reduction gear 115 is mounted on a second pin 130, and the pinion of the first reduction gear 115 meshes with a gear on the carriage bracket 110. A second reduction gear 116 is mounted on a third pin 131, and the pinion of the second reduction gear 116 meshes with a large gear of the first reduction gear 115. A first motor 117 is mounted on a sheet metal bracket 109 and meshes with the second reduction gear 116. With this design, the ink cartridge 112 can rotate back and forth within a 180° range to achieve fan-shaped printing of the printhead. The advantage of fan-shaped printing is that rotation is simpler than translation, and accuracy is easier to achieve. Ink scraping and sealing are performed on both sides of the middle shell 101, resulting in a smaller overall printer size. The width required by translation design is reduced by 20%, thereby increasing the portability of the portable photo printer by adopting fan-shaped printing.

[0033] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
